Return the superclass of *type*. If the second argument is omitted the super
|
||||
object returned is unbound. If the second argument is an object,
|
||||
``isinstance(obj, type)`` must be true. If the second argument is a type,
|
||||
Return the superclass of *type*.
|

|

Calling :func:`super()` without arguments is equivalent to
|
||||
``super(this_class, first_arg)``. If called with one
|
||||
argument the super object returned is unbound. If called with two
|
||||
arguments and the second argument is an object, ``isinstance(obj,
|
||||
type)`` must be true. If the second argument is a type,
|
||||
``issubclass(type2, type)`` must be true.
|
||||
|
||||
A typical use for calling a cooperative superclass method is::
|
||||
|
||||
class C(B):
|
||||
def meth(self, arg):
|
||||
super(C, self).meth(arg)
|
||||
def method(self, arg):
|
||||
super().method(arg) # This does the same thing as: super(C, self).method(arg)
|
||||
|
||||
Note that :func:`super` is implemented as part of the binding process for
|
||||
explicit dotted attribute lookups such as ``super(C, self).__getitem__(name)``.
|
||||
explicit dotted attribute lookups such as ``super().__getitem__(name)``.
|
||||
Accordingly, :func:`super` is undefined for implicit lookups using statements or
|
||||
operators such as ``super(C, self)[name]``.
|
||||
operators such as ``super()[name]``. Also, :func:`super` is not
|
||||
limited to use inside methods: under the hood it searches the stack
|
||||
frame for the class (``__class__``) and the first argument.
